MACHINE FOR ROLLING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 452,141, dated May 12, 18 91.

Application filed June 25, 1888. Serial No. 278,104. (No model.)

To all whom-'1. it Hwy-concern.-

Be it known that 1, JOHN LIDDELL, of New Haven, in the county of New Haven and State of Connecticut, have invented new Improvements in Machines for Rolling Paper Tubes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters and figures of reference marked. thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

and 10, detached views illustrating the clutch mechanism between the shaft Yand the loose pulley d; Fig. 11, a modification.

This invention relates to an improvement in the machine for the manufacture of paper tubes from which cartridge-shells are made. These tubes are usually formed by taking a sheet of paper of the required size, pasting one surface, then rolling the sheet upon a mandrel into tubular shape, the paste causing the several convolutions of the paper to adhere to each other. The paper is thin, so that each tube is composed ofseveral convolutions or thicknesses. Generally this rolling of the tube has been performed by hand.

The object of my invention is to produce a machine, which, receiving a blank sheet of paper out to the required size, will automatically paste the surface and roll the sheet into the required tubular shape, and discharge the completely-rolled tube from the machine and it consists in a revolving mandrel surrounded by a series of revolving rollers, combined with a pasting and feeding device, which will deliver the pasted sheet between the said revolving mandrel and the surrounding rollers whereby the paper so fed will be wound upon the mandrel, the surrounding rollers serving to press the successive convolutions one upon another to cause the pasted surface to adhere and form the tube, and with mechanism for discharging the thus formed tube from the mandrel, as more fully hereinafter described.

A represents the bed of the machine, upon which the operative mechanism is arranged; B, the mandrel which is supported in a bearing C at one end, the mandrel projecting from the said bearing over the bed. The said mandrel is caused to revolve by the application of power thereto in any. convenient manner, here represented as by a pulley D, to which a crank-handle E may be applied. The length of the mandrel should be somewhat greater than the length of the tube required to be made.

F F represent a series of rollers, more or less in number, the illustration showing four such rollers. These rollers are supported in hearings in a frame G parallel with the mandrel B. The-frame is of segment shape,as seen in Figs. 4 and 5, and the bearings of the several rollers are in a segment of a circle of" which, as seen in Fig. 4, the axis of the man- So drel is the center, and so that the said rollers when surrounding the mandrel, as seen in Fig. at, come substantially into contact with the said mandrel B. The frame is open upon one side, the rollers inclosing but about one, 8 half the circumference of the mandrel.

The frame G is hung upon an axis H, so that the frame with the rollers may be turned away from the mandrehas from the position seen in Fig. 4 to that seen in Fig. 5, so as to take the rollers out of contact with the man drel or return to bring them into working engagement with the mandrel, as seen in Fig. 4.

I represents another roller, like the rollers F, but is arranged in a slide J in the frame 5 G, so as to move toward or from the mandrel B, as from the position Fig. 4: to that seen in Fig. 5 or return. This sliding movement of the rollcrI is necessary in order that the frame may be turned away from the mandred to remove the rollers, as I have described.

In rear of the mandrel the pasting and feeding apparatus is arranged.

K represents the reservoir in which the paste or other suitable adhesive material is placed, over which a revolving roller L is arranged parallel with the mandrel, but so that the surface of the said roller may dip into or so as to receive acoating from the adhesive material in the reservoir. A continuous rotation is imparted to the roller L in the direction indicated by the arrow by means of an endless band M, running from pulley N on the mandrel to a pulley O on the pasteroller shaft, as seen in Figs. 1 and 2. Above the roller L is a pressure-roller I, so that paper introduced between the pressure-roller and the paste-roller will receive a coating of paste from the paste-roller upon its under side.

Between the paste-roller and the mandrel is an endless apron R, the upper surface of which runs toward the mandrel, and so that the paper passing from the paste-roller onto the endless apron will be carried toward the mandrel and deliver the advancing edge of the paper between the mandrel and the roller F immediately below it. The mandrel, revolving in the direction indicated by an arrow, operates in connection with the said roller immediately below it to engage the advancing paper. Then the continued revolution of the mandrel with the roller below itadvances the edge of the paper to the second roller, thence to the third roller, thence to the fourth roller, thence to the roller I, and so on, each revolution of the mandrel adding one eonvo lution of the paper until the sheet is cornpletely taken up. The mandrel revolving between the surrounding rollers causes the paper to be pressed hard upon the mandrel, and so that the adhesive material will properly cause the several convolutions to adhere one to another, and thus complete the tube.

I find it desirable in the commencement of the operation at least to give the rotation to the several surrounding rollers independent of the contact between the mandrel and the rollers, and this is conveniently done by constructing the several rollers F with a pulley 8, (see Figs. 1 and 2,) which pulleys work in frictional contact with a corresponding pulley on themandrel-shaft, (indicated in broken lines, Fig. 2,) so that the said rollers F operate in conjunction with the mandrel to draw the paper onto the mandrel. After the rolling has been completed, as described, the frame carrying the rollers is turned away from the mandrel, as indicated in Fig. 5.

The swinging movement is imparted to the frame G from a cam T 011 the shaft Y (see Fig. 7) through a lever U hung beneath the bed, which is connected to the frame by a rod V, as seen in Figs.'2 and 7, and so that at the proper time the cam T will release the lever U, which under the action of the spring u will move the rod V downward, and thereby swing the frame G outward and upward from the mandrel, as seen in Fig. 5. In this swinging movement of the frame G the slide J, which carries the roller I, also receives a movement to take it away from the mandrel, and which movement is produced by means of a stationary cam \V, projecting upward from the bed, over which a slot a in the slide J passes, and so that the said stationary cam, working in said slot, will force the slide J with the roller I away from the mandrel. Springs 1) are provided, the tendency of which is to force the slide J and its roller I toward the mandrel, these springs yielding to the action of the cam W to permit the withdrawal of the slide.

The shaft Y is arranged in suitable bearin gs parallel with the mandrel and is adapted forintermittentrotation. To impart such rotation, a loose pulley (Z is arranged on the shaft Y, and from which an endless band runs from a pulley e on the mandrel, as seen in Figs. 1, 2, and (i. The loose pulley (Z is adapted to be engaged with the shaft Y by a clutch thrown in by hand or otherwise at the proper time. The clutching mechanism may be any of the well-known clutches adapted to couple a pulley with the shaft; but I will hereinafter describe a clutch mechanism peculiarly adapted for this purpose.

The rotation of the shaft Y is produced when the rolling operation is complete, and so as to throw the frame G away from the mandrel, as before described.

To discharge the tube from the mandrel, a collar or sleeve f is arranged upon the mandrel, (see Fig. (3,) there being an extension q from the collar down through a slot h in the bed parallel with the mandrel. is free to slide longitudinally on the mandrel and normally stands at the bearing end of the mandrel. At the proper time, and after the frame G has been turned away from the mandrel, the collarf is moved along the mandrel, and in such movement strikes theinner end of the tube on the mandrel, and, continuing its movement, forces the tube along the mandrel to a point beyond the surface on which the tube was formed, and maybe so as to entirely discharge the tube from the mandrel, and as from the position seen in Fig. 6 to that in broken lines, same figure. Then the collar returns. The frame is also returned to bring the rollers again into working engagemerit with the mandrel, and a second tube is formed as before. In the completion of the second tube the collar f is again forced f0rward, and in moving the second tube as it did the first it would throw the first tube from the mandrel if it were not discharged under the fitst movement of the collar. This intermittent reciprocating movement of the collar f is produced from the shaft Y by means of a cam i on the shaft Y, which cam at the proper time imparts a horizontal sliding movement The collar j" ICC to a slide Z, arranged in suitable bearings par allel with the shaft Y, as seen in Fig. 3. This slide is connected to the collar f by means of a lever m, hung upon a fulcrum a beneath the bed, one arm of the lever connected by a link 0" to the said slide, and the other arm to the collar, as seen in Fig. 6, and so that as the shaft Y revolves, the cam t' will impart a movement to the slide Z, which'will cause the lever m, and with it the collar f, to be moved to the position indicated in broken lines, Fig. 6, before mentioned. The card t' is timed with relation to the cam T so that the discharging or ejecting operation of the tube occurs while the frame G is in the open position.

The rolling of the tube with the frame in the closed position may be continued indefinitely and until the requisite amount of rolling has been produced upon the tube. Then the pulley at, being clutched with the shaft Y, the opening of the frame G and the discharge of the tube will be produced. Immediately upon the. discharge the slide Z escapes from the cam 1', when a spring t will return the slide 1 and the collar f to their place of rest or normalposition. At the same time the 'cam T operates the lever U, which through the rod V returns the frame G to the working position.

To impart a rubbing action to the outer edge of the paper of which the tube is formed which will correspond somewhat to the hand operation in the usual method of forming the tubes, and so as to insure the perfect adhesion of that edge, I arrange a rubber 2, which is in the form of a lever hung upon a fulcrum 3, and so as to swing in a plane substantially parallel with the mandrel, but upon that portion of the mandrel which is outside the rolling operation, as seen in Fig. 1. The vibratory movement is imparted to this rubber by means of a cam 4 on the shaftYand a reacting spring 5, and so that as the rolled tube is moved along the mandrel in the discharging operation the said rubber 2 will operate upon the surface of the tube which still revolves with the mandrel, and thus will produce a spiral zigzag rubbing action upon the outer surface of the tube as the tube is being forced from the mandrel.

The clutch mechanism for engaging the pulley d with the shaft Y is illustrated in Figs. 8, 9, and 10. The pulley dis arrangedloose upon the hub 6 of the cam 2, as seen in Fig. 9, which makes the pulley substantially loose upon the shaft Y.

In a radial slot in the hub 6 of the cam a clutch-pin 7 is arranged. This pin is adapted to move radially, forced outward by means of a spring 8 in the hub when the pin is free for such movement. In the pulley at one point is a corresponding notch 9, and so that when the notch 9 of the pulley comes into line with the clutch-pin 7, the clutch-pin being free, the spring will force the clutch-pin into the notch 9 of the pulley, as seen in Fig. 10, and

so that the clutch-pin will engage both the pulleyand cam; but. if the clutch-pin bethrown the hub and pulley, as seen in Fig. 9, and in the path of the projecting clutch-pin a dog 10 is hung, so as to swing in a plane parallel with the plane of the pulley, the dog being constructed with a beveled nose, as shown. If, therefore, the dog be thrown down, as seen in Fig. 10, the clutch-pin will be free to drop into engagement with the pulley, as before described, and so long as they are so engaged, the pulley and cam will revolve together; but if the dog he raised, as seen in Fig. 8, then as the pulley and cam revolve, the clutch-pin will strike the bevel-nose of the dog 10, and riding up that incline the clutch-pin will be forced from its engagement with the pulley, as seen in Fig. 8. The dog is operated by a clutchlever 11, whichnormally leaves the dog in the up or disengaging position, where it is yieldingly held by a spring 12; but if the lever 11 be turned, as seen in Fig. 10,the dog will be forced out of the path of the advancing pin, and so as to permit engagement between the pulley and cam on shaft Y. One revolution only of the shaft Y is intended, because that single revolution produces the discharge of the tube, and in that revolution the frame G is first opened. Then the discharge of the tube commences, and during that discharge the cam 4 imparts the vibratory movement to the rubber, as seen in broken lines, Fig. 1. The clutching operation may be produced at any time when it shall appear to the operator that the rolling operation is complete, and as soon as the clutching is produced between the pulley and the shaft G, the clutching-lever may be released, and then on the completion of the revolution of the shaft Y the clutch-pin will be thrown out of engagement,

For the clutching mechanism which I have illustrated either of the many known clutching devices which are adapted to be thrown out of or into engagement at a predetermined point in its revolution may be employed.

While I prefer to employ the sliding roller I in the roller-frame that roller may be omitted, the rollers which are in stationary bearings in the frame being sufficient to produce a satisfactory rolling operation in connection with the mandrel.

It will be understood that the rolled tube may be stripped from the mandrel in various waysas, for illustration, it may be drawn therefrom by hand. Hence I do not wish to be understood as necessarily including a discharging or ejecting mechanism.
